1. f(-6)=12

2. k(-4)=-68

Further explanation:

We have two functions whose values we have to find on certain points.

In order to find the values of function, the value is put in place of variable in the function.

So,

<u>1. f(a) = -2a</u>

We have to find, f(-6)

So putting -6 in function

f(-6) = -2(-6)\\= 12

<u>2. k(x) = -3x^2+5x</u>

We have to find, k(-4)

So putting -4 in function

k(-4)=-3(-4)^2+5(-4)\\=(-3)(16)-20\\=-48-20\\=-68

The cost of health insurance is $900 per month. The cost of an operation for a dramatic injury is $500,000. The chances of someo
lord [1]

Answer:

Yes, It is better to buy the insurance.

Step-by-step explanation:

Given Data:

Cost of Health Insurance for a month = 900$ per month

As 20 Years = 20*12 months = 240 months

Cost of Health Insurance for 20 years = 900 * 240

Cost of Health Insurance for 20 years = 216,000$

Insurance claim in case of having dramatic injury = Cost of Dramatic Injury = 500,000$

Insurance claim in case of having no dramatic injury = 0$

Chances of dramatic injury in 20 years = P(A) = 47.3%

Chances of not having dramatic injury in 20 years = P(B) = 100% - 47.3%

Chances of not having dramatic injury in 20 years = P(B) = 52.7%

Expected Insurance Claim for 20 years:

Expected Insurance Claim for 20 years = (Chances of having dramatic injury in 20 years * Insurance claim) + (Chances of not having dramatic injury * Insurance claim)

Expected Insurance Claim for 20 years = P(A) * 500,000$ + P(B) * 0$

Expected Insurance Claim for 20 years = 47.3% * 500,000 + 52.7% * 0

Expected Insurance Claim for 20 years = 236500 + 0

Expected Insurance Claim for 20 years = 236,500$

Expected Profit:

As expected insurance claim is 236,500$ is more than the cost of health insurance for 20 years and we are expected to have profit of 20,500$, thus we should take the health insurance.

emmasim [6.3K]

Matt earns $4 and $3 for 1 load of laundry and 1 load of dishes respectively

<u>Solution:</u>

Given, Matt gets paid at home for doing extra chores.

We have to find How much does Matt earn for completing each type of chore?

Let the amount for 1 load of laundry be m and amount for 1 load of dish be n.

Now, last week, he did 6 loads of laundry and 1 load of dishes, and his parents paid him $27.

Then, 6 \times amount for 1 load of laundry + 1 \times amount for 1 load of dish = 27

\rightarrow 6 \mathrm{m}+\mathrm{n}=27 \rightarrow(1)

The week before, he finished 1 load of laundry and 9 loads of dishes, earning a total of $31

Then, 1 \times amount for 1 load of laundry + 9 \times amount for 1 load of laundry = 31  ⇒m + 9n = 31 ⇒ (2)

Now let us solve equations (1) and (2)

0 – 53n = - 159

-53n  = -159  

53n = 159

n = 3

Now, substitute n value in (1) ⇒ 6m + 3 = 27 ⇒ 6m = 24 ⇒ m = 4

Hence, matt earns $4 and $3 for 1 load of laundry and 1 load of dishes respectively.
